Today's photo is a wild black eyed Susan (Rudbeckia hirta) that I found along the roadside last summer. While these are a common sight in Maine in mid to late summer, this one is unique because it has a double bloom. The wild black eyed Susan typically has a single bloom with one layer of petals and looks like a yellow daisy with a brown center. Cultivated varieties of Rudbeckia come in a variety of colors with both single and double blooms. Some cultivated varieties produce bright, variegated flowers with rich shades of brown or bronze radiating from the center.
